摘要

在瑞士斯雷茨农业科学中心对30头断奶的东巴尔干猪品种进行了试验。本研究的目的是确定补充牛至提取物对东巴尔干品种断奶仔猪生产能力和健康状况的影响。这些动物被分为两组,每组15只,雄性8只,雌性7只。试验开始时,ⅰ组(对照)的活重为8150 kg,ⅱ组(对照)的活重为8160 kg。对照组饲喂小麦:大麦(50:50),试验II组每100 kg饲料中添加50 g牛至提取物。试验结束时,ⅰ组活重19.646 kg,ⅱ组活重20.673 kg。在东巴尔干品种断奶猪的饲料中添加牛至提取物(Origanum vulgare)提高了平均日增重(8.96% ~ 0.146 kg对0.134kg),每公斤增重饲料系数降低了8.22% (5.240kg对5.709 kg)。

STUDY OF THE INFLUENCE OF OREGANO EXTRACT SUPPLEMENTATION IN WEANED PIGS OF THE EASTERN BALKAN BREED
An experiment with 30 weaned pigs of the East Balkan pig breed was conducted at the Agricultural Science Center in Sredets. The aim of the study was to determine the effect of oregano extract supplementation on the productivity and health status of weaned pigs of the East Balkan breed. The animals were divided into two groups of 15 animals, 8 males, and 7 females. The experiment started at 8,150 kg live weight for group I (control) and 8,160 kg for experimental group II. The animals from the control group received wheat: barley (50:50), and 50 g of oregano extract per 100 kg of feed was added to the ration of animals from experimental group II. The experiment finished at 19.646 kg live weight for group I and at 20.673 kg live weight for those in group II. The use of oregano extract (Origanum vulgare) in the feed for weaned pigs of the East Balkan breed improved the average daily gain (by 8.96%-0.146 kg vs. 0.134kg) and reduced the feed conversion ratio per kg gain by 8.22% (5.240kg vs. 5.709 kg).
